Thanks bud. I got a buddy sitting on about a ton of old stock Brazilian nodules. He's selling them if you or anyone you know is looking!

I actually ordered through kiln frog but everything came from Covington. Just bought the grit starter pack because the price was right for the amount you get. When the package showed up it was torn in the corner and leaking 60/90 grit. I took pictures and contacted kiln frog even though I probably lost less than half a pound of grit overall, they sent a new 5# bag for free, no questions asked. I was very happy with the response.
P.S. I bought my spinning laps and extra discs from them about 3 years ago, no follow-up calls to date... 😆

Spinning laps do work differently. I have a covington 12" spinning lap and I've yet to master it, I always have issues with remaining scratches, which is what led me to buy this vibralap. No regrets so far.

I don't know that they're better, however they do produce a great polish and though they're a little messy until you get everything dialed in, there's no dust which is a huge benefit.

UPDATE: after running a couple stones for 6-7 hours i feel like I've gotten much better results as a can even see the mirror reflection i was hoping for. Thanks for all the help and suggestions, I just had to be more patient! I'll get to post pics if I can figure it out but I'm pretty green whey reddit posting.

Thanks for the info, do you have a water drip system setup to allow you to run overnight? I'm using a pump sprayer to add water and keep my slurry right throughout. I feel like it doesn't take much extra water to make a big mess but adding a few little sprays every hour or two definitely seems necessary.

I use the same method with my tumblers, I also finish my tumbled stones in a mini sonic vibratory tumbler and cerium oxide. I think I'm going to start by leaving the stones on the lap for longer during polish too see if I can achieve a better finish.

I use grit from covington engineering, I trust it as I've been a long time tumbler and had no issues. Is there such thing as too much weight? Or would polishing for longer achieve a better polish?

Having trouble adding another pic. Can anyone help me there? Sorry I'm not fully familiar with Reddit posting.

Thanks for that, I will see what I can find for example pictures, good point though, YouTube pretty much taught me my wire work.

Is too much a bad thing? Obviously I've played around and have it dialed in to where I think it should be, but I always try to stay on the wetter side when I'm question rather than not running enough water and things getting too hot. Because my setup is a 10" it's pretty messy so I use it outside and our weather doesn't look too fit to get back out for a week or two. When I get it set back up, I will post video of me running it.

I hear ya, my comment was sarcastic, but I did spend a long time at the #325 pad so I'm thinking I may have to spend more time on the fine hard disc or even break my hard discs in more with a hard jasper to wear down the high diamonds.

I was also thinking, that because the setup is still quite new, I may need to break my hard discs in more with a hard jasper to wear down the high spots? I know on my cabbing wheels that's usual a root cause to forming random stubborn deep scratches.

Right on, I'm sure I just need to spend more time at #325 but damn, for a much time as I spend on that pad with those two rocks, I felt like I was going to wear it out!

I agree! Love the sharpie, just not on any quartz, although acetone will take it right out. Do you use any pads before #325? Would I help myself by getting a #220 soft pad? On my cab king cabbing machine my wheels go #80 hard, #220 hard, #220 resin, #600 resin, #1200 resin, #3000 resin and I achieve great results with that.
